Term scattering more of a general process

Click For Summary

Discussion Overview

The discussion revolves around the term "scattering" and whether it serves as a general process that includes the linear effects of reflection, refraction, and diffraction. Participants explore the definitions and contexts in which these phenomena occur, examining their relationships and distinctions.

Discussion Character

  • Debate/contested

Main Points Raised

  • Some participants suggest that the term "scattering" could encompass reflection, refraction, and diffraction, depending on the context.
  • One participant argues that reflection, refraction, and diffraction occur in non-homogeneous media, while scattering is associated with homogeneous media.
  • A later reply asserts that the reflected wave is termed the "scattered" wave and that the refracted wave is referred to as the "internal" wave, indicating a relationship between these concepts.
  • Another participant notes that diffraction is inherently linked to the shape of the scatterer, providing an example of Mie scattering where the scattered wave maintains spherical symmetry.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the definition of scattering and its relationship to reflection, refraction, and diffraction, indicating multiple competing views remain.

Contextual Notes

The discussion highlights the dependence on context and definitions, as well as the conditions under which these phenomena are analyzed, but does not resolve these complexities.

term “scattering” more of a general process

Is the term “scattering” more of a general process which incorporates the linear effects of reflection, refraction and diffraction?

Depends on the context.
 
Reflection, refraction, and diffraction don't happen in a homogeneous medium. Scattering does.
 
In short, Yes.

- The "reflected" wave is referred to as the "scattered" wave.
- The "refracted" wave is referred to as the "internal" wave.

The scattered and internal fields are calculated by applying the boundary conditions at the particle interface.

Diffraction occurs as part-and-parcel of the shape of the scatterer. For example, if the scatterer is spherically symmetric (Mie scattering), the scattered wave will be spherically symmetric as well.
